Qualitative modeling concerns the representations and reasoning that people use to understand continuous aspects of the world. Qualitative models formalize everyday notions of causality, and provide accounts of how to ground symbolic, relational representations in perceptual processes. Qualitative models describe what phenomena might be relevant in a situation and support reasoning about what outcomes might occur. Qualitative analyses frame the use of quantitative knowledge, making them important in understanding expert performance as well as everyday reasoning. There is ample evidence that people use intuitive mental models in reasoning about the world, and that mental models also play important roles in expert performance. Qualitative modeling provides formal representations for such mental models. Qualitative reasoning has been used to create systems that help engineers and scientists, including tools for designing, monitoring, and troubleshooting complex systems, conducting experiments and analyzing data in human-like ways. Qualitative reasoning also has great potential for education, since its representations and reasoning techniques appear to be similar in useful ways to those people use. Consequently, qualitative reasoning is of interest to researchers in Artificial Intelligence, Cognitive Science, as well as many areas of science and engineering.


The 24th International Workshop on Qualitative Reasoning will be held in Portland, Oregon, USA, from August 8th through August 10th. It is co-located with the 32nd Annual Conference of the Cognitive Science Society which runs August 11-14, also in Portland.


We seek papers on qualitative reasoning and qualitative modeling, including:


         Qualitative modeling of particular areas in physical, biological and social sciences, and in engineering.

  • Representations and techniques for qualitative reasoning.
  • Methods of integrating qualitative reasoning with other forms of knowledge, including quantitative methods and other formalisms.

         New ways to use qualitative reasoning for tasks such as diagnosis, design, monitoring.

         Applications of qualitative reasoning, including education, science, and engineering.

         Cognitive models of qualitative reasoning, including use of existing QR formalisms for cognitive modeling and using ideas and results from other areas of cognitive science for qualitative reasoning.

         Using qualitative reasoning in understanding language, sketches, images, and other kinds of signals and data sources.

         Formalization, axiomatization, and mathematical foundations of qualitative reasoning.



All papers must be submitted via the conference submission web site, by May 19, 2010. All submissions must be in PDF format, and can be one of the following types:

  • Full Paper: Not to exceed 6000 words, excluding references.
  • Poster: Not to exceed 6000 words, excluding references.
  • Brief Ideas/Viewpoints: Exactly one page in the workshop format (see below).


Review Process. All submissions will be selected according to their quality, significance, originality, and potential to generate discussion. Each contribution will be reviewed by at least two referees from the QR-10 Program Committee.


Submission to Conferences or Journals. The accepted papers will be published as a collection of Working papers. As QR-10 is a workshop, not a conference, submission of the same paper to conferences (e.g., AAAI-10) or journals is acceptable.


Format. Papers should be formatted according to the AAAI-10 guidelines, available from, and must be in PDF format. 


The workshop is also open to people who would like to attend without submitting a paper or a poster.
